The rapid development of artificial intelligence (AI), especially generative AI (GenAI), has already brought, and will continue to bring, revolutionary changes to our daily production and life, as well as create new opportunities and challenges for diagnostic and therapeutic practices in the medical field. Haihe Hospital of Tianjin University collaborates with the National Supercomputer Center in Tianjin, Tianjin University, and other institutions to carry out research in areas such as smart healthcare, smart services, and smart management. We have conducted research and development of a full-process disease diagnosis and treatment assistance system based on GenAI in the field of smart healthcare. The development of this project is of great significance. The first goal is to upgrade and transform the hospital's information center, organically integrate it with existing information systems, and provide the necessary computing power storage support for intelligent services within the hospital. We have implemented the localized deployment of three models: Tianhe "Tianyuan", WiNGPT, and DeepSeek. The second is to create a digital avatar of the chief physician/chief physician's voice and image by integrating multimodal intelligent interaction technology. With generative intelligence as the core, this solution provides patients with a visual medical interaction solution. The third is to achieve deep adaptation between generative intelligence and the entire process of patient medical treatment. In this project, we have developed assistant tools such as intelligent inquiry, intelligent diagnosis and recognition, intelligent treatment plan generation, and intelligent assisted medical record generation to improve the safety, quality, and efficiency of the diagnosis and treatment process. This study introduces the content of a full-process disease diagnosis and treatment assistance system, aiming to provide references and insights for the digital transformation of the healthcare industry.

Objective To investigate the surgical method and clinical outcome using the free anterolateral thigh flap with the medial gastrocnemius artery as the recipient artery for the repair of complex wounds in the lower leg. Methods A retrospective analysis was conducted on the clinical data of 11 patients with complex wounds in the lower leg admitted to Suzhou Ruihua Orthopedic Hospital from October 2020 to September 2022. All patients had extensive skin and subcutaneous soft tissue defects in the lower leg and received free anterolateral thigh flap repair with the medial gastrocnemius artery as the recipient artery. The skin of donor site was directly sutured. Results All 11 free skin flap survived in 11 patients, and both the donor and recipient sites healed in stage I. All patients were followed up after discharge, with a follow-up time of 12 to 35 months. The follow-up results at 12 months postoperatively showed good wound healing, good flap appearance and elasticity, restoration of normal knee and ankle joint function, and independent living ability. The donor site wounds healed well without significant scar hyperplasia. At the last follow-up, the flap sensory function was graded as S₃ in 2 patients and S₂ in 9 patients. The functional score of the affected limb was excellent in 5 patients and good in 6 patients, with an excellent and good rate of 100%. Conclusion The medial gastrocnemius artery has a suitable vessel caliber for anastomosis and a constant location. The use of the free anterolateral thigh flap with this artery as the recipient artery for the repair of severe wounds in the lower leg can effectively cover soft tissue defects and avoid injuring the residual main vessels in the lower leg, resulting in satisfactory outcomes.

Objective:Exploration on the mechanism of acupuncture-targeted therapy for rheumatoid arthritis and identification of candidate Chinese materia medica.Methods:Targets of acupuncture for RA were collected from related literature, and GSE205962 gene chips were obtained from GEO database. The weighted co-expression network (WGCNA) was constructed by screening differentially expressed genes using R 4.3.1. The collection targets were taken to intersect with the differential genes, and the common genes were obtained for high-throughput GO and KEGG enrichment. The Hub genes were screened by constructing protein interaction networks using the String database and Cytoscape 3.9.0 software. The CIBERSORT algorithm was used to explore the mechanisms of RA immune infiltration, and finally the Coremine Medical database was applied to predict Chinese materia medica.Results:A total of 8 key targets were selected (RHOA, JAK1, FYN, LCK, STAT1, STAT3, EGF, GATA3). The results of immune infiltration analysis showed that various immune cells were closely related to the biological processes of rheumatoid arthritis, including γδ T cells, monocytes, regulatory T cells, CD8 T cells, etc. Saposheikovize Radix, Cinnamomi Ramulus, Anemarrhenae Rhizoma, Dendrobii Caulis, Rehmannine Radix, Lonicerae Japonicae Flos, Pinelliae Rhizoma, Cimicifugae Rhizoma, Poria, Stephaniae Tetrandrae Radix were the 10 kinds of commonly used key Chinese materia medica in the treatment of RA.Conclusions:Acupuncture and moxibustion may treat RA by regulating RHOA, JAK1, FYN, LCK and other core targets. This study predicts that Chinese materia medica can be used as a source of drugs for the treatment of RA, and can provide new ideas for the combination of acupuncture and medicine for the treatment of RA.

Objective:To explore the clinical effects of free anterolateral thigh perforator flap pedicled with descending genicular artery in repairing wounds after lower leg limb-sparing surgery.Methods:A retrospective observational study was conducted. From January 2019 to June 2021, 12 patients with wounds after lower leg limb-sparing surgery who met the inclusion criteria were admitted to Suzhou Ruihua Orthopedic Hospital, including 6 males and 6 females, aged 17 to 74 years, with original wound area ranging from 17 cm×9 cm to 40 cm×15 cm. Five patients had infection in wounds. The wounds were all repaired by free anterolateral thigh perforator flap from contralateral thigh, with area of 18 cm×10 cm to 37 cm×9 cm. The artery of flap was anastomosed with the descending genicular artery, and the wounds in donor areas were sutured directly. Seven patients were transplanted with split-thickness skin grafts from the contralateral thigh to cover the remaining wounds that can not be covered by flap and the wounds in donor areas were covered with gauze. During the operation, the types of perforating branch carried by flap and the types of arteries and veins in recipient areas were recorded. The survival and occurrence of vascular crisis of flap, the survival of skin graft, the wound healing in donor and recipient areas, and the length of hospital stay after flap transplant surgery were recorded. During follow-up, the color and texture of flap, reinfection in lower leg, and fracture healing were recorded. At the last follow-up, the limb salvage function of patients was evaluated according to the functional evaluation criteria of Chen Zhongwei's amputated limb replantation.Results:The types of perforating branches carried by flaps were as follows: 6 cases of only carrying the descending branch of the lateral circumflex femoral artery, 3 cases of only carrying the oblique branch of the lateral circumflex femoral artery, and 3 cases of carrying the descending branch of the lateral circumflex femoral artery and oblique branch of the lateral circumflex femoral artery after internal pressurization anastomosis. The types of arteries in the recipient area of flap were as follows: one case of main trunk of the descending genicular artery, 8 cases of the saphenous branch of the descending genicular artery, and 3 cases of the articular branch of the descending genicular artery. The types of veins in the recipient area of flap were as follows: 8 cases of one accompanying vein of the descending genicular artery and one branch of the great saphenous vein, and 4 cases of two branches of the great saphenous vein. All the flaps survived without vascular crisis, and all the skin grafts also survived. The wounds in the donor and recipient areas were all healed. The length of hospital stay of patient after flap transplant surgery ranged from 13 to 79 days. During the follow-up of 6 to 23 months, the color and texture of flap were both good, with no infection in lower leg wound. Internal or external fixation were removed after fracture healing in 5 patients, and bone graft internal fixation was performed in 7 patients whose fractures were not healed after surgery and all the incisions healed without infection. At the last follow-up, the limb salvage effect of patients was evaluated as followings: excellent in 7 patients, good in 4 patients, and fair in one patient.Conclusions:Free anterolateral thigh flap pedicled with descending genicular artery can effectively repair the wounds after lower leg limb-sparing surgery and control infection with short length of hospital stay, while not increasing the risk of secondary injury of distal limb vessels. Thus, it can obtain satisfactory limb salvage effect which is worthy of clinical promotion.
